Description

Sensoreinrichtung für Kraftfahrzeuge zur Einklemmerkennung bei einem beweglichen Flügel, der in eine Endlage überführbar ist.Sensor device for motor vehicles for pinch detection with a movable wing that is in an end position is transferable.

Derartige Sensoreinrichtungen (z.B. US-A- 3 830 018) sind auf vielfältige Weise bekannt. Häufig wird aus den Leistungsdaten einer elektromotorischen Antriebseinheit für den Flügel eine Information über einen möglichen Einklemmfall entnommen. Der Motorstrom oder das vom Motor abgegebene Drehmoment steigen dann stark an. Probleme ergeben sich insbesondere bei längerem Betrieb durch mögliche mechanische Reibungserscheinungen zwischen dem Flügel und einer in der Regel vorgesehenen mechanischen Führung. Ein derartiger normaler Betriebsfall ist nur schwer von einem tatsächlichen Einklemmfall zu unterscheiden.Such sensor devices (e.g. US-A-3 830 018) are in a variety of ways known. The performance data often becomes an electromotive Drive unit for the wing an information taken about a possible trapping case. Of the Motor current or the torque delivered by the motor increase then strong. Problems arise in particular with prolonged operation due to possible mechanical signs of friction between the wing and one usually provided mechanical guidance. Such a normal one Operating case is difficult from an actual one Differentiate between pinching.

Es sind auch mechanische Tastgeber bekannt, die insbesondere in eine Dichtung eingearbeitet sind, in die der Flügel in seiner Endlage einfährt. Dabei stehen sich beispielsweise kapazitiv wirkende Flächen gegenüber, die im Einklemmfall in ihrem Abstand verändert werden. Das Problem dabei ist die Unterscheidung zwischen dem Einklemmfall und dem Einlaufen des Flügels in seine Endlage, bei der derselbe Effekt eintritt. Im Einklemmfall ist erforderlich, schlagartig eine elektromotorische Antriebseinheit abzuschalten oder sogar in ihrer Bewegungsrichtung umzukehren. Würde man dies auch beim Einlaufen des Flügels in seine Endlage tun, so könnte dieser nicht die vorgeschriebene Endlage tatsächlich erreichen, da es in dieser notwendig ist, die Dichtung elastisch zu verformen.Mechanical pushbuttons are also known, in particular are incorporated into a seal in which the wing retracts in its end position. For example, capacitive-acting surfaces opposite that in In the event of jamming, their distance can be changed. The problem here is the distinction between the jamming case and the entry of the wing into its end position the same effect occurs. In the event of jamming, it is necessary suddenly an electromotive drive unit switch off or even in their direction of movement to reverse. Would you do this even when entering the wing in its end position, this could not be the actually reach the prescribed end position since it is in this is necessary to elastically deform the seal.

Der Erfindung liegt die Aufgabe zugrunde, eine Sensoreinrichtung der eingangs genannten Art zu schaffen, mit der es möglich ist, einen Einklemmfall sicher und zuverlässig zu erkennen und nur in diesem Fall schnell und sicher die erforderlichen Notmaßnahmen zu ergreifen.The invention has for its object a sensor device of the type mentioned at the beginning with which it is possible to get a jam case safely and reliably to recognize and only in this case quickly and safely the take necessary emergency measures.

Die Erfindung löst diese Aufgabe durch die kennzeichnenden Merkmale des Patentanspruchs 1.The invention solves this problem by the characterizing Features of claim 1.

Wesentlich für die Erfindung ist, daß der Druckwandler und seine Betätigungsmechanik räumlich entkoppelt sind. Dadurch ergibt sich eine konstruktive Variationsvielfalt, die es ermöglicht, die Sensoreinrichtung an den jeweiligen Einsatzfall anzupassen.It is essential for the invention that the pressure transducer and its actuation mechanism are spatially decoupled. This results in a variety of designs, which enables the sensor device to be attached to the respective Adapt the application.

Durch das Zusammenwirken des Druckwandlers mit dem Vorsprung der Hohlraumwand kann der Vorlauf für das Ansprechen des Druckwandlers variabel eingestellt werden. Unter Vorlauf ist der Weg zu verstehen, den der Vorsprung bis zum Erreichen des Druckwandlers zurücklegen muß. Dieser Weg kann zwischen Null und dem Abstand des Druckwandlers zu der gegenüberliegenden Wand variieren. Damit ist es auch möglich, mechanische Toleranzen auszugleichen. Durch das Zusammenwirken des Vorsprungs mit dem Druckwandler kann die Ansprechcharakteristik des Druckwandlers, d. h., die Änderung seines Ausgangssignals an die jeweiligen Einsatzbedingungen hinsichtlich der Stärke der zu detektierenden Kraft und des Auslösewegs angepaßt werden. Unter Auslöseweg ist der Weg zu verstehen, der für die maßgebliche Signaländerung des Druckwandlers durch den Vorsprung zurückzulegen ist.By the interaction of the pressure transducer with the projection the cavity wall can be the lead for the response of the pressure transducer can be set variably. Under Preliminary run is to understand the way that the lead up to reach the pressure transducer. This Can travel between zero and the distance of the pressure transducer vary to the opposite wall. So that's it also possible to compensate for mechanical tolerances. By the interaction of the projection with the pressure transducer can the response characteristic of the pressure transducer, i. H., the change of its output signal to the respective Conditions of use with regard to the strength of the detected Force and the release path can be adjusted. Under Trigger path is to understand the path that is relevant for the Signal change of the pressure transducer through the projection is to be covered.

Die Anwendung der Erfindung bei Kraftfahrzeugen ist an verschiedenen Stellen möglich. Zu nennen sind dabei vor allem elektrisch angetriebene Fenster, ein Schiebe-Hebedach, ein Cabrio-Verdeck oder eine Tür, die mit Servounterstützung von einer Vorrast- in eine Schließstellung gebracht wird.The application of the invention to motor vehicles is on different positions possible. To be mentioned here all electrically powered windows, a sunroof, a convertible top or a door with power assistance from a pre-locked to a closed position brought.

In the drawing, an embodiment of the invention is shown. It shows
Fig. 1
a cross section through a sensor device according to the invention and
Fig. 2
the sensor device of Fig. 1 in detail.

Der Schnitt von Fig. 1 zeigt einen Türrahmen 1 mit einer nachgiebigen Abdeckblende 2. Zwischen dem Rahmen 1 und der Blende 2 befindet sich ein Körper 3 aus elastischem Material, der vergrößert in Fig. 2 dargestellt ist. Der Körper 3 besteht aus einem keilförmigen Abschnitt 4 und aus einem Hohlraum 5 mit gegenüberliegenden Wänden 6 und 7. Ein Endstück 8 hält den Körper 3 in der eingezeichneten Lage.The section of Fig. 1 shows a door frame 1 with a flexible cover 2. Between the frame 1 and the panel 2 is a body 3 made of elastic Material that is shown enlarged in Fig. 2. Of the Body 3 consists of a wedge-shaped section 4 and from a cavity 5 with opposite walls 6 and 7. An end piece 8 holds the body 3 in the drawn Location.

Der Rahmen 1 dient als Anschlag für eine elektromotorisch bewegbare Fensterscheibe 9, die in Richtung eines Pfeils 9' verfahrbar ist. In der Endlage der Scheibe 9 wirkt eine nicht dargestellte Dichtung zwischen Scheibe 9 und dem Fensterrahmen 1.The frame 1 serves as a stop for an electric motor movable window 9 in the direction of an arrow 9 'is movable. In the end position of the disc 9 acts a seal, not shown, between disc 9 and the window frame 1.

Innerhalb des Hohlraums 5 befindet sich ein Druckwandler 10, der beispielsweise in Form eines Foliendrucksensors aufgebaut ist. Ein derartiger Sensor ist aus der DE 30 44 384 C2 bekannt. Die Wand 6 besitzt einen Vorsprung 11, der spitz zuläuft und auf den Druckwandler 10 ausgerichtet ist sowie einen nach außen gerichteten Vorsprung 12, der den Hohlraum 5 gegen den Rahmen 1 abstützt.A pressure transducer is located within the cavity 5 10, for example in the form of a film pressure sensor is constructed. Such a sensor is from the DE 30 44 384 C2 known. The wall 6 has a projection 11, which tapers to the pressure transducer 10 is aligned as well as an outward projection 12, which supports the cavity 5 against the frame 1.

Im Normalfall läuft die Scheibe 9 in die Endlage ein und wird dort nach Stillsitzen des Antriebs gehalten. Durch Bewegungsumkehr wird die Scheibe 9 entgegen der Richtung des Pfeils 9' bewegt und gibt schließlich die Fensteröffnung frei. Kommt es beim erneuten Hochlaufen zu einem Einklemmfall, so wird der eingeklemmte Körper (nicht dargestellt) durch die Scheibe 9 gegen die mit F bezeichnete Stelle der Blende 3 gedrückt. Aufgrund der Eigenelastizität der Blende 3 wird diese nach oben verschwenkt und nimmt beispielsweise die strichliert eingezeichnete Stellung ein. Da der Rahmen 1 starr ist, verringert sich der Abstand zwischen der Blende 2 und dem Rahmen 1. Durch die Wirkung des Vorsprungs 12 wird die Bewegung der Wand 6 begrenzt, während die Wand 7 und damit der Druckwandler 10 noch die Bewegung fortsetzt. Schließlich dringt der Vorsprung 11 in die Oberfläche des Druckwandlers 10 ein, dessen Ausgangssignal sich dadurch deutlich verändert. Als Ausgangssignal kann beispielsweise der Widerstandswert des hier verwendeten Foliendrucksensors verwendet sein.In the normal case, the disc 9 runs into the end position and is held there after the drive has stopped. By Reversal of movement is the disc 9 against the direction arrow 9 'moves and finally gives the window opening free. If there is one when starting up again Pinching case, the pinched body (not shown) through the disc 9 against the designated F Place the aperture 3 pressed. Because of its own elasticity the aperture 3 is pivoted upwards and takes the position shown in dashed lines, for example a. Since the frame 1 is rigid, the Distance between the panel 2 and the frame 1. By the The effect of the projection 12 is the movement of the wall 6 limited while the wall 7 and thus the pressure transducer 10 still continues the movement. Finally he penetrates Protrusion 11 into the surface of the pressure transducer 10, whose output signal changes significantly. The resistance value can be used as the output signal, for example of the film pressure sensor used here be.

Die Blende 2 wird nur im Einklemmfall in der beschriebenen Weise bewegt. Im Normalfall bleibt die Blende in der eingezeichneten Ausgangslage. Durch die Gestaltung der Vorsprünge 11 und 12, den Abstand dieser Vorsprünge vom Türinnenblech bzw. der Oberfläche des Druckwandlers 10 und die Charakteristik des Druckwandlers 10 lassen sich entsprechend den jeweiligen Anforderungen unterschiedliche Vorlaufwege bis zum Ansprechen des Druckwandlers 10 vorgeben. Ist es gewünscht, bei relativ geringen Kräften möglichst unmittelbar auf einen Einklemmfall zu reagieren, so kann der Abstand zwischen dem Vorsprung 11 an der Oberfläche des Druckwandlers 10 möglichst gering gehalten werden. Die Kontur des Vorsprungs 11 kann innerhalb der fertigungstechnischen Möglichkeiten so groß wie möglich sein. Schließlich kann auch durch die Charakteristik des Druckwandlers 10 die Ansprechempfindlichkeit beeinflußt werden. Es sind derartige Wandler bekannt, bei denen bereits bei geringer Flächenpressung eine starke Änderung ihres Gesamtwiderstands auftritt, die mit einer nachgeschalteten Elektronik dann problemlos detektiert werden kann.The aperture 2 is only described in the case of pinching Way moved. Normally the aperture stays in the drawn starting position. By designing the Projections 11 and 12, the distance of these projections from Inner door panel or the surface of the pressure transducer 10 and the characteristics of the pressure transducer 10 can be different according to the respective requirements Advance paths until the pressure transducer responds 10 pretend. It is desirable with relatively low forces react as immediately as possible to a trapping situation, so the distance between the projection 11 on the Surface of the pressure transducer 10 is kept as small as possible will. The contour of the projection 11 can be within the manufacturing technology as large as possible be. Finally, the characteristics of the Pressure converter 10 affects the sensitivity will. Such converters are known, in which already a strong change at low surface pressure their total resistance occurs with a downstream Electronics can then be easily detected can.

Weitere Einflußfaktoren für die Charakteristik der erfindungsgemäßen Sensoreinrichtung sind die Elastizität der Blende 2 sowie die Gestalt des Keils 4, insbesondere seine Erstreckung innerhalb des Raumes zwischen dem Rahmen 1 und der Blende 2. Durch den Keil 4 wird etwa an der Übergangsstelle zum Hohlraum 5 ein Lagerpunkt 13 geschaffen, um den herum die Blende 2 mit dem Hohlraum 5 schwenkbar ist. Durch das Zusammenspiel der verschiedenen Faktoren läßt sich die Charakteristik der Sensoreinrichtung in weiten Bereichen variieren und an die jeweiligen Einbauverhältnisse sowie Auslösungskriterien für nachgeschaltete Sicherheitsmaßnahmen, hier Stillstand bzw. Bewegungsumkehr des Scheibenantriebs, anpassen.Other influencing factors for the characteristic of the invention Sensor device are the elasticity of the Aperture 2 and the shape of the wedge 4, in particular its extension within the space between the frame 1 and the aperture 2. The wedge 4 is approximately at the Transition point to the cavity 5 created a bearing point 13, around which the aperture 2 with the cavity 5 is pivotable. Through the interaction of the different The characteristics of the sensor device can be factors vary widely and to the respective Installation conditions and trigger criteria for downstream Safety measures, here standstill or reversal of movement of the disc drive, adjust.
